Answer:
slope = 4
Step-by-step explanation:
We can find the slope of a line when knowing 2 points by using the slope formula, 
. 
and 
represent the x and y values of the first point, respectively. 
and 
represent the x and y values of the second point, respectively.
The two points we have are (2,8) and (0,0). So, in this case, = 2, = 8, = 0, and = 0. Let's substitute those values into the formula and solve to get the slope:
So, the slope is 4.
<span>The null hypothesis states that a population parameter is equal to a value. The null hypothesis is often an initial claim that researchers specify using previous research or knowledge. ... The alternative hypothesis is what you might believe to be true or hope to prove true.</span>
Answer:
Step-by-step explanation:
you divide
6x = n²-16
n²-6x-16=0 -16=-8*2, -6=-8+2
(n-8)(n+2)=0
n-8=0, n+2=0
n=8, n=-2
Negative solution is -2.
